C++ (Cpp) free_stmt Examples

Example #1

File: Fl_Query.cpp Project: GustavoMOG/efltk

void Fl_Query::disconnect() {
    if (m_database) {
        close();
        free_stmt();
        m_database->m_queryList.remove(this);
        m_database = NULL;
    }
}

Example #2

File: pl_funcs.c Project: 0x0FFF/postgres

static void
free_stmts(List *stmts)
{
	ListCell   *s;

	foreach(s, stmts)
	{
		free_stmt((PLpgSQL_stmt *) lfirst(s));
	}

Example #3

File: unparse.c Project: welterde/NuMOO

void
unparse_program(Program * p, Unparser_Receiver r, void *data,
		int fully_parenthesize, int indent_lines, int f_index)
{
    Stmt *stmt = decompile_program(p, f_index);

    prog = p;
    receiver = r;
    receiver_data = data;
